Building a fetal immune system is crucial for newborn survival, requiring coordination with the maternal system to fight infection and prevent harm. This review explores immune cell development, organization in mucosal sites, and implications for diseases like prematurity.
Area of Science:
- Developmental immunology
- Fetal and neonatal immunity
- Tissue morphogenesis
Background:
- The fetal immune system must balance protection against pathogens with tolerance of the mother.
- Immune cells play critical roles beyond defense, influencing tissue development.
- Early life immune function, particularly in mucosal tissues, has lasting health impacts.
Purpose of the Study:
- To review the establishment of immune system cellular constituents by hematopoietic and lymphoid organs.
- To examine the organization of immune cells in the gut and lung for early life immunity.
- To highlight key pathways in prenatal immunity using examples of diseases.
Main Methods:
- Review of current literature on fetal and neonatal immunity.
- Analysis of immune cell development and organogenesis.
- Examination of disease models including prematurity and inborn errors of immunity.
Main Results:
- Hematopoietic and lymphoid organs collaborate to form the immune system's cellular components.
- Immune constituents are organized in the gut and lung, impacting long-term health.
- Diseases of prematurity and inborn errors of immunity illuminate prenatal immune pathways.
Conclusions:
- The development of a functional fetal immune system is essential for fetal and newborn survival.
- Immune cells contribute to tissue morphogenesis, with significant implications for development.
- Understanding prenatal immunity is vital for addressing diseases affecting newborns.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.

Development of the Lymphatic System
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
